6l State of New York, have invented certttin new and useful Improvements,in Tv eis a specification.

My invention relates to typ'ewritinv mai Tating mechanism for suchmachines. I

My invention has for its principal obJect lo provide an improvedcoluninq'umpeiy or means for quickly and conveniently bringing thecarriage to any selected one of a plurality of column positions,intermediate desired.

In the accompanying drawings, Figure 1 .20 is a front to rear verticalsectional view of the mechanism. Fig. 3 is a to ,plan viewof themachine. Fig. 4 is a ragrnentary front elevation of partof themechanism, parts' of the main framebeing Shown 'in vertical section.Fig. 5 is a view of' part of- 430.1the mechanismv in horizontal sectionon the line mof Fig. 6. Fig; 6 is a fragmentary View of'part of themechanism in vertical section substantially-cna line y-.-f1/ of Fig. 5.

ln the several views'l have shown only so much of a typewriting'machineas is necessary to illustrate my invention and parts have beenomitted'or! broken or shown .in section as has been found convenient.

ends in brackets 29 and -3() Saidcarriage comprises end pieces 12 inwhich is pivoted the shaft of a roller laten 13. The carriage rail '9 isinclined rownward'toward the front of the machine at an angle of about45. The lower forward rail 11 has secured theretoa feed rack 14 thatmesheswith two gear wheels 15,'and 16both loosely mounted on a naled atits front and rear ends respectively in frame plates 18 and 19 dependingfrom the top plate 7 The gear-Wheel 15 is operatively connected in anysuitable manner with a spring 2O co'xfiled Within a barrel-or drum 21which is yalso mounted on the shaft 17;

and. this spring acting tlirough'said gear wheel l'drives the carriagein letter space feed direction. f

Themotion' of the carriage under the iinpulse of the spring 20 iscontrolled-by any suitable cscapement mechanism comprising anescapernent Wheel geared to a shaft 22 which is jou'rnaled at its endsin the frame plates 18 and 19. Said shaft has mounted thereon a pinion23 with freedom to rotate on the shaft but held against motionlongitudinally of `saidshat, said pinion meshing with the gear wheel 1G.Said pinion 23 or its hub has its rear-face formed Wit-hra-tchet clutchteeth that adapted to mesh withl like teeth formed mythe forvard end ofa col-lar 24 that is loosely mounted on the shaft 22 and the rear end ofwhich is connected by a tooth and slot connection with a collar 25 thatis fastv on or integral with the shaft 22. The collar 24 is yieldin'glypressed into shaft 17 which is jouiu;

engagement with the hub -of the pinion 23 by a spring 26 compressedbetween flanges- "of the collars 25 and 24. The construction issuch thatwhen the shaft 22'is held against rotation the carriage is held againsttion under the impulse ofthe spring20; i' Aif the righitg* he thefcollar24 slip past one another.

In order to release ythe carriage from its eseapement mechanism it isonly necessary to-force the collar 24 ytoward the rear of 26. To thisend said collar is fo'imedwith a peripheral groove into end of an arm 27of a vertically disposed rocking member 28 that is 'vote which" extendsthe me themachine against the tension of its spring limit-said claims.tofthe precise form of eeific forme( -of the stops 34 has its lower forkor arm projeetingtoward the front of thMmjachine s. engagement with stoparms or teeth 36 pro-A l l 3i' that rigidly Amounted on a vertical shaft38, the u per end of which is journaled in claims I have also referredto said stop" tmfrecited the claims.

Ward the front of the machine from'the frame plate 19. It will .beevident that 1f the arm Q7 be pressed toward the rear of the machine thecarria e will heI released from its escapement mecianism.

A column stop bar 31 is mounted on the carriage, being suspended bylarms32 from a rod that joins the side plaies 12 'of the carriage near theupper rear ends'of said plates. The arms B2 hang sul'istantially.vertical and the stop bar 31 is situated just hack ofI and nearly on alevel with the top plate 7, Said stop bar 31 is formed on its upper andlower faces with transverse notches a letter space distance apart andcolumnstops 34 are adapted to be mounted on said stop bal'. Said columnstops are of furcated construction and are adapted to he .slipped on tothe bar from the rear, the forks of the stops enihracin{g` said bar andfitting into the notches formed in said bar. As shown in the presentinstance, each of said stops has riveted to one sidethereof a platespring 35 that is adapted. to enter the notch on the lower side of thebar and by its resiliency to cause a frictional engagement between thestop and the edge of the notch so as to prevent accidental displacementof the stop from its position on the bar. Each slightly in advance ofthe-bar 31 and theseprojoctingjarms are 'adapted to come into jectingfrom a rotary toothed stop member the top p ate' 7 'and the lower en dof which projects through the back plate 2v and vis ]ournaled in 'abearing' 39 secured to said hack plate.

In theoperation of the machine this toothed stop member is opposed tothe column stops'B-t'v andl in some ofthe claims I have accordinglyreferred to said columnstops astabulator stopsand to the rotary stopmember .as a counter-stop' Inasmuch this counter-stop comprises aplurality of arms or teeth', each of which in itself is a stop, 'I havealso in some of the claims re ferred lto said-rotary stop member asfacom-v 'poundA counter-stop and -in some' of 'A the arms-or teeth asa setof counter-stops. doV not mean these expressions, howeverftolcounter-stop or set" of counter-stops shown in this case, bu-txl regard"the x referredftei-faS-fing i distinctly recited/ 11i s'aidclimsf--Iln- .thel

ot rotation, that is to say, to the axis of the vertical shaft 38, andsome lof the claims are limited to a construction in which the faces ofthe di'erent stops have this relation; but

is not necessary that the faces of said'stops be thus related., As faras I am aware it is broadly `new to provide a plurality of carringestops each mounted on a rotary. meml ber that-is rotated hy the carriageto bring one oranother of said stops to operative position, whether ornot said stops be Situated on the rotary member in such relativepositions that a plane at, right an les to the "axis of said rotarymember woul vintersect the, faces of the stops. It will also be observedthat the faces-of these several stopsBG lie in planes that intersect oneanother. In the present instuncethese planes intersect substantially inthe axis of the shaft 38.

The column stops or tabulator stops 34 and the counter-stop or set ofcounter-stops are normally out of coperative relation and means arerovidedfor establishing' a cooperative r'e ation between these two setsof stops. As shown in the present instance, one of these sets of stopsis n ormall out of the path of the other, but is mova le into .the

. path of theother, and in the present instance it is the counter-stopor set of counterstos thatis thus made movable.- To this en the shaft 38ismade movable up and down in itsLbearings. i

The upward motion of, the shaftv 38 is limited by the contact of thetoothed member 37 with the upper bearin ofthe shaft, and vits downwardmotion 'is limited-by a collar 40- making Contact with .the bea ing 39.The shaft normally stands in its lower position, sh'ovvn in F-ig.- 1,.withthe teeth. 36 out ofthe 'path of the column Sto sfvfbutsaid shaft isadapted to be raisedllto bring saidteeth into the path of said'stops b'means that will resently be described.'

Yl`ahulator keys 57 are mounted on 5 the upper ends o'l' the stems5t.

in the present instance the levers l52m-e arranged side by side andclose together throughout thegreater part ot their length, hut neartheir rear ends all ot' the levers ex 0 cept the tirst are formed withotl'set bends as shown in Fig. 3 in order to space the stop portions 51of said levers a suitable distance- 'apalt At their forward ends thelevers 52 are preferably heut, as shown in Fig. 3, so 5 -as to bringrall of the keys 57 into a straight line fore and aft ot the machine. lherear ends ol the key levers 5i). are guided in vertical slots ltormed inthevplate 48.

The construction is such thatwhen any of said key7 levers is operated hy de- ,prer-:sing theappropriate key 57, the unil) versai har is elevated, the shait 07 is'rocked toward the rear otlv the machine and the shaft 38 is raised hythe arm (Bti, thus bringing thestop teeth 3G into the path of the columnstops Bt.

In orderv to avoidreleasing the carriage before the arms 36 are raised into the path ofthe column stops, there is lost motion between the arm Tl and theeross-piece 72, as indicated in Fig. 1. The stop teeth 3i) are so'designed that each ol? the column stops 34 in passing said stop pieceengages one of said teeth and turns the `rotary stop member a unitsdistance, thus bringing the next succeeding tooth 3(3.into positionl tohe engaged hy the next succeedingvcolunni stop 34 and turning the shaft3th The shaft. 38 and pinion 42 will draw the har 44 toward theleft'until the shoulder .50 is arrestedl hy the stop port-ion 5l of thcoperated key lever.

If the third or fourth key lever is operated thccarriage will he arrested 'hy thc third ori'oui-th' column stop and at.the third or fourth column position.v

.l'n order to prevent backward rotation of the sha't after it has heenpartially turned hy one of the column stops and before the next arm 3l;is engaged by the next succeeding columnV stop, a detent `78 `is tmounted inthe lug 45 just above the raek bar 44, the disposition of theparts being such that when the shaft, 38 is in its elevated'position thepinion 42 is in engagement with the detent 78; but when-the parts are intheir norinalv position said pinion isi out, of engagement, with saiddetent. The detent 78 consists of a squared plungerseated .in a suitableopeningl in the lug'lt and having a. rounded stein 79 thatfits into around hole in said lug. The stem 79 is hollow, as shown in Fig. 5, and aspring 80 is= seated in said stem and compressed between the detent 78and the inner end of the 3 hole in which the stem 7 9- is seated. The

spring 80 tends to press the deten't toward t e front of the machine,its motion being limited ,by the plate 47 as indicated in Fi 5. Theouter end of the detent 1s ma e square and lits into a square opening soas to prevent rotation;' and the end of the detent is formed as shown inFi 5 with an edge that is adapted to enter -t e space betweenstwo teethof the pinion 42. Said edg f has-'an abrupt face adapted to prevent bacward rotation of said lpinion and an inclinedl face which renders t edetent lmovable by -a tooth of the pinion when the shaft is turned by acolumn stop.

A being indepen entl The operationof my tabulator or column jumperwillnbe understood 'from the forego- 1n description. Any desired numberof co umn stops 34 may be placed on the bar 31 and suitabl locatedthereon, the stops adjustable along said bar. I'it 1s desire to brin thecarriage to the third columnl osition, or example, vthe tabulator keymar ed 3 I will be depressed,

-this key being connected with the third key lever 52 from the-left; Therear end of the lever 52will velevate the universal bar 70,4

thus rocking the shaft 67 and elevating the shaft 38 and releasing thecarriage by the arm 71 engaging the cross piece 72. The elevation of theshaft 38 has brought the arms 36 into the path of the column stops andhas also brou ht the pinion 42 into en agement with ytle detent 78. Thefirst coumn stop will strike the first arm 36 and will move this armoutof the path' of the sto s and the next succeeding arm into the pat ofthe sto s, rotating 'the shaft 38 a units distance, in w ich position itwill be retained by the detent 7 8: The second stop will strike thesecond arm 36 vand willmove it and the shaft 38 in the same manner, thusturning said shaft" 38 a second units distance and bringing the shoulderclose to the operated key lever., 4The third column sto therefore, willbeunable to turn the sha t 38 and 50 will be arrested by the third stoparm 36. When the key is released the sleeve 24-will move toward thefront of the machine, bringingfits clutch teeth again into engage'- mentwith the clutch teeth on the pinion 23, thus retaining the carriage inthe position where it has been arrested. The shaft 38 will drop to itslower position, thus' bringing 4the armsv 36 out of the paths of thestops 34 and leaving the carriage free to move either way withoutinterference vby saidv f arms 36. The-pinion; 42 will escape from thedetent 78 xand the spring 61 will restore ,the bar 44 toits normalposition in which it is arrested by a pin 81 projecting from said Vbarand'engagingthe plate 48. In this position the lirst arm 36 isw'ih theposition Ashown in Fig. 2, that is to'say, it in .such position thatwhen the shaft 38 1s again column keys but it will be obvious that any idesired number maybe provided. If, in the :present construction, it isdesirable -to use more vkthan four column stops the carriage can bebrought toany column beyond the fourth by a plurality of operations ofthe keys. For example, if it is desired to bring the carriage to theseventh column position, this' can be done by operating the fourthcolumn key, thus'bringing the carriage to the fourth position and thenoperating the third column key which will result in the carriagebeing-arrested .by the seventh column stop. By reference to Fig.4 itwill be seen that' the shoulder-50 will move a short distance before itwill be arrested by 'the first column key so that when this key isoperated 4the first arm 36 moves alittle to the left under the impulseof Kthe column stop .and whenvthe key 1s released the stop returns toits normal position. This, taken together with the fact that there is aslight lost motion in the connection between the carriage and itsescapement mechanism, will insure that'the stop 34'will come to rest tothe left of the arm 36 so that in case the tabulator is operated twicewithout any intervening operation of the escapement, the column stop rstarrested will have passed to a position where it will not interfere-withthe`second raising of the' shaft 38. 1

The escapement mechanism may be of any suitable sort. xIn the presentinstance, I have showna small universal barV 84 mounted on a lever 85andv situated near thev printing point in position to be struck by a-contact portion 86 of the type bar 87 1ivh'en the latter is thrown upto print.` The lever 85 #on whichthe universal bar is mountedis pivotedat 88 to a bracket 89 secured to the front face of the frame plate 18.In said bracket there is journaled a shaft 90, having at its lower end askew pinion 91, meshin with a gear wheel 92 mounted on the sha 22.` Atits upper end, the shaft carriesa single tooth 93 that is .controlled byfeed dogsf94 on` the lo'wer end of the lever-'85. The construction issuch that when the universal bar 84 is struck by vany type bar, thelever 85 is oscillated and the toctli is-teni leased, permitting theshaft 90 to makeondl complete rotation, thus imparting letterspace feedto the carriage.

It will be observed that my column Jumper is of such construction thatit is not necessary to make any difference between theA different columnstops A34 as has been usual A heretofore 1n column` jumper mechanisms.

A column is selected'notby-selecting a col-1A by registering, or, inlefi'ect,`connting, or

tion 'with the carriage and escapenienbnief-h I stop, etc.

keeping tally of the column stops as they pass the rotary member 37. Thefirst key arrests the Erst stop that reaches said rotary member, thesecond key arrests the second arrest the third column stop. the secondvkey will be depressed instead of the third. It will be obvious that thiscounting or registering of the column stops may be effected by meansdiffering greatly from that here shown. As far as I am aware thisprinciple is .broadly new in tabulator mechanism and my claims areintended to cover broadly all tabulator devices made in accordance with.said principle. i v

lVhen the carriage is at its extreme righthand position the column ortabulator stops all face the counter-stop, and in the present instancevin which said column4 stops are mounted on the carriage, the column ortabulator sto which is then next to or Which .pruxiinatey facesthecounter-,stop is the first stop from the left end of the stop bar.l't. will be 'understoodtha/t thecolumn or tabiilator stops /niay bemade to coact suc? cessively .with he counter-stops as theA carriagetravels.A toiv'ard lthe le it. andthat by pressing the properkey a tablatorfstop bel-l liindi'iorlin the present instant` tothe right f' of,th/atpi'hi'ch proximately faces said coun.-l

t'er-stop,"mayl'bc made to coact with. said counter-stop to effect thearrestof the carriage after it is released from the step-by- .stepfeeding mechanism and before it is otherwise nisin.

Various other changes besides those indicated in the body of thespecification may7 be made in the detailsof construction and arrangementwithout departing from my invention.
